* With regard to the speciee which have received different designations in the Eeigen
and Adamsian catalogues, whether those names be retained of which the specimens exist,
and have been widely distributed, in accordance with the diagnoses, or whether the prior-
ones be adopted of which the unique types do not represent the descriptions, is a matter
of little moment to the writer of the Brit. Mus. Cat. He spared no pains in making-out
his predecessor's species before describing his own, and has offered the best attainable
ligfc of the parallel forms in the review here quoted.

* In Donovan's 'Naturalist's Repository,' vol. ii. 1834, p. 61, appears (without
authority) " Valuta Dufresnii, Don., California, S. America."

t This belongs to a group of species in which the cartilage is semi-internal, intermediate
between Scrobicularia ( = Lutricoltt) and Macoma. They are arranged under the former
group in Add. Gen. ii. 409, as "subgen. Capsa, Bosc." That Lamarckian name being in
common use for Ipkigenia, Schum., and being also employed for Asaphis and Gastrana, it
adds to the confusion to use it for a fourth group. The bulk of Blainville's old genus
having migrated to Lutraria and Scrobicularia, his name may bo revived for this group
not otherwise provided-for. The species was redescribed in consequence of Duwliyi having
been lei't among the true Tellens in. Mus. Cum.

The following species appear in later numbers of the Proceedings :

365. Volsella splendida, Dkr. California.

Dr. Gray, in his elaborate article on the divides, 1858, pp. 38 et seq.,
gives 0. julieta, Duel., 0. araneosa, Lam., and 0. venulata, Lam., as syno-
nyms of Strephona reticularis, Lam. ; and quotes as " species (?) more or less
allied to it," 0. polpasta, Duel., 0. splendidula, Duel., " O.jaspidca,l)iid.,=
0. Dmlosii, Rve." [?], 0. Tcaleontina, Duel. (Gallapagos), 0. Curningii, Rve.,
and Oliva Schumacheriana, Beck, "California: front of pillar-lip brown"
[?=(9. Cumingii, var.].

For 0, volutella, Lam. (including 0. razamola, Duel.), he constitutes tho
genus Ramola.

For 0. undatella, Lam. (including 0. tTiieroglypliica, Rve., 0. nodulina,
Duel., and 0. ozodina, Duel.), and similar species, he forms the genus
A.nazola.

The restricted genus Olivella is altered to Olivina, and includes (from the
West Coast) 0. gmcilis,$by., 0. anazora,Ducl., 0. tergina, Duel., 0. lineolata
= dama, Goodall*; and, in a section, 0. columellaris, Sby., 0. semisulcata,
Gray, and 0. zonalis. Lam.

The California!! species, 0. biplicata, Sby., = 0. nux, Goodall, in Wood, is
placed in the genus Scaphula. This is constituted for an animal, " Olivancilld
auricuJaria," D'Orb., on which, in his work on S. America, he figures the
shell of 0. biplicata (teste Gray). The shell might in some way have become
mixed with S. American specimens ; but as D'Orb. could not possibly have
there observed the living animal, the genus should be restricted to the latter.
The shell of 0. biplicata is very peculiar, and has not been found south of
San Diego. D'Orbigny's genus is Olivancillaria.

In the second part of Morch's "Review of the Vermetidce" 1861, pp.
326-365, occur the following. A portion of the genus Bivonia is united to
Spiroylyphus. Petaloconchus, Ahtes, and part of Bivonia are united to Ver-
metus, Morch (non auct.). The name Aletes appears to be used in a varietal
sense, in no respect according with the subgenus as described by the author.

* I was perhaps wrong in referring the Mazatlan shells to Val.'s species ; but if Mr.
Morch is right in his own determination, the Mazatlan synonymy and locality must be
expunged. There was no evidence of a typical Siphonium when the Reigen Catalogue was
published, nor have I seen such from the whole coast, unless ih> minute operculum h y
Brit. Mus. Col., tablet 2537, be supposed the young. Morch says, " the lid is unknown."
The operculum of the similar Mazatlan species, on which the subgenus Aletes was
founded, is described in Maz. Cat. p. 302.

f " Cpr.'s observations respecting Chenu's plates (Maz. Cat. p. 306, lin. 18) are in part
erroneous, it being overlooked that Chenu has two plates marked ' V.' :" note *, p, C37t

* Mr. Morch has not seen any laminae inside, but, from the 3-5 spiral lirse on the
columella, believes they will be found. The opercula supposed to belong to this species
(Maz. Cat. p. 311) Mr. M. thinks more probably those of Spiroglyphus albidus. He
states (erroneously) that the shell was not opened by the describer.

f Morch supposes that Bivonia contorta, Cpr., may be the adult of Petaloconchus
macrophragma, and that both may be forms of Aletes centiquadrus. The nuclear por-
tions are, however, quite distinct, and the three shells appear, from beginning to end, as
far removed as any ordinary Vermetids can be from each other.

J The writer doubts respecting this species, and think% the shell on which it is para-
sitical to be a Melo, and not Strombus galea, simply because named after Peron, who
did not visit this dislnuu

* The present posture of binomial nomenclature is well illustrated in this most elabo-

operculum-spine is figured in plate 25. f. 16, is quoted as " Siphonium (Stoa) subcre-
natum, v. spinosa" The shell described in Maz. Cat. p. 307 is quoted as " Vermetus
(Thylacodus) contortus, var. y. contortula (Thylacodus}, forma 1, Thylocodus (?) con-
tortux, var. indentata, Cpr." Perhaps the sentences of Klein and the early writers are
more easy to understand and remember. The Chilonida of Middendorff (v . First Keport,
p. 214) are simple in comparison,
